LP221M250E1P3 Equivalent & Substitute Parts Reference

Part Overview

The LP221M250E1P3 is a 220 µF, 250 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can snap-in package. This component is classified as Active product status and is designed for general-purpose applications requiring stable capacitance and voltage ratings in through-hole mounting configurations.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative manufacturers meeting identical electrical and mechanical specifications. The LP221M250E1P3 has documented equivalent alternatives that maintain functional compatibility within the same application parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP221M250E1P3 is determined by strict adherence to the following core parameters:

Mandatory Matching Parameters:

• Capacitance: 220 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 250 V (exact match required)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (substitute must support this range)
• RoHS Compliance: ROHS3 Compliant (exact match required)

Secondary Parameters (Performance Characteristics):

• ESR (Equivalent Series Resistance): Varies by manufacturer; lower values indicate better performance
• Lifetime @ Temperature: Varies; higher values indicate longer operational life
• Ripple Current Ratings: Varies; affects thermal performance under AC conditions

The substitute part B43504A2227M000 meets all mandatory matching parameters and is therefore classified as a direct equivalent.

Engineering Selection Recommendations

LP221M250E1P3 (CDE) - Primary Selection: The LP221M250E1P3 is the recommended primary component for new designs. It maintains Active product status, ensuring continued manufacturer support, availability, and technical documentation. This part is suitable for applications where long-term supply chain stability is required.

B43504A2227M000 (EPCOS - TDK) - Substitute Selection: The B43504A2227M000 is a functional equivalent meeting all mandatory electrical and mechanical parameters. However, this part carries "Not For New Designs" status, indicating that EPCOS - TDK Electronics has discontinued active development and support for this component. This part is appropriate for:

• Replacement or repair of existing equipment
• Applications where supply of the primary part is unavailable
• Situations where extended component lifetime (3000 Hrs @ 105°C vs. 1000 Hrs) provides operational advantage

Physical Dimension Considerations: The B43504A2227M000 exhibits different physical dimensions (smaller diameter, greater height) compared to the LP221M250E1P3. While lead spacing and mounting type are identical, PCB layout verification is required to confirm that the substitute part fits within the available board space without mechanical interference.

Both parts maintain ROHS3 compliance and identical electrical ratings, ensuring regulatory and functional compatibility within the specified application parameters.

Frequently Asked Questions (FAQ)

Q: Can B43504A2227M000 be used as a direct replacement for LP221M250E1P3 in existing designs?

A: B43504A2227M000 meets all mandatory electrical specifications (220 µF, ±20%, 250 V, polar, through-hole, 10mm lead spacing). However, physical dimensions differ: the substitute is smaller in diameter (22mm vs. 30mm) but taller (32mm vs. 25mm). PCB layout verification is required to confirm mechanical fit before substitution.

Q: What is the significance of "Not For New Designs" status on B43504A2227M000?

A: This designation indicates that EPCOS - TDK Electronics has discontinued active development and support for this component line. The part remains available from existing inventory but is not recommended for new product development. Use this part only for replacement applications or when the primary part is unavailable.

Q: Are the ESR and lifetime differences between these parts critical for substitution?

A: ESR and lifetime are secondary performance characteristics. B43504A2227M000 exhibits lower ESR (580 mOhm @ 100 Hz vs. 1.13 Ohm @ 120 Hz) and extended lifetime (3000 Hrs @ 105°C vs. 1000 Hrs). These differences may provide operational advantages in thermal or ripple current environments but do not prevent functional substitution when primary electrical parameters match.

Q: Do both parts require identical PCB footprints?

A: Both parts use identical lead spacing (0.394" / 10.00mm) and through-hole mounting, so PCB pad patterns are compatible. However, the different physical dimensions (diameter and height) require verification that the substitute component physically fits within the available board space without contact with adjacent components or board features.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8532.22.0040) codes. No regulatory or compliance barriers exist to substitution.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -40°C to 105°C. This range is identical, ensuring thermal compatibility in applications spanning this temperature spectrum.
